Question

A) x/2=8
B)x/2= -8
C)x/4= -5

Answer 1

A) x/2=8

x= 8 • 2

x= 16

B)x/2= -8

x= - 8 • 2

x= - 16

C)x/4= -5

x= - 5 • 4

x= - 20

Answer 2

Resposta:

A)

x/2 = 8

2 • x/2 = 2 • 8

2÷2 • x/2÷2 = 2 • 8

1 • x/1 = 2 • 8

x = 2 • 8

x = 16

B)

x/2 = - 8

2 • x/2 = 2 • (- 8)

2÷2 • x/2÷2 = 2 • (- 8)

1 • x/1 = 2 • (- 8)

x = 2 • (- 8)

x = - 16

C)

x/4 = - 5

4 • x/4 = 4 • (- 5)

4÷4 • x/4÷4 = 4 • (- 2)

1 • x/1 = 4 • (- 2)

x = 4 • (- 2)

x = - 20
